Part-time street lighting for two residential areas of Exeter

The lights will go out in Cowick and Alphington for five hours overnight

Some street lights in a Devon city will be switched off at night to help save money and cut carbon emissions, a local authority says.

Devon County Council said 1,000 street lights would be switched off at night in Exeter.

The lights will go out in Cowick and Alphington at 00:30 BST and come back on again at 05:30.

The council is responsible for nearly 77,000 street lights, which cost £3.4m in electricity.

Lighting on main roads and busiest routes in the city would remain unchanged, the council said.

Councillor Stuart Hughes, the cabinet member for highways, said: "The changes will help cut carbon emissions and costs.

"At the outset, we set a target to save 4,000 tonnes of carbon from these changes, and that has already been achieved."

Students and some residents in Exeter have previously raised safety concerns about the plans.

The University of Exeter Students' Guild said: "The money being saved is at extreme detriment to safety."
